wmnow' sasn Application filed April 12, 1929. Serial No. 854,556.'

This invention relates to new and useful improvements in sashes for windows, and

- aims to provide a sash of the sliding type, which in the present instance, is equipped with a glass panel frame capable of being rotated within the sash frame in order thatthe inside and outside of the glass panel may be quickly and without danger washed by one within the building. This obviously therefor, will overcome the necessity of the window washer leaning or disposing himself outside the window frame, which is an ever dangerous procedure.

An important object of this invention is to provide a sash of the foregoing type that is of very simple and inexpensive construction, the same embodying but few parts, and these so co-related as. to reduce the possibility of a panel frame in reverse position from that disarrangement to a minimum.

The foregoing and other objects of the invention will be readily apparent to those skilled in the art after a consideration of the following specification and accompanying drawings, wherein Figure 1 is a perspective of my improved sash as arranged within a window frame, the glass panel frame of the sash being disclosed as swung to open position, which is a position that may be employed when it is desired to ventilate the room, and this without requiring the raising of the sash.,

Figure 2 is a horizontal sectional viewthrough the u per end of the sash frame looking downwar 1y upon the panel frame when in closed position. Y

Figure 3 is a fragmentary inside elevation x of a window frame equipped with a pair of my improved sashes.

Figure 4 is an enlarged fragmentary view partially in longitudinal section through the upper endof my sash, the panel frame being closed. I Figure 5 is a horizontal section through the upper end of one of the sashes as arranged within the window frame, and looking downwardly upon the rotatable panel'frame, the full and dotted line positions thereof clearly indicating the manner in which the panel frame mgy be completely turned around within the s Figure 6 is a horizontal section taken through the u per end of the sash frame,- and looking ownwardly upon the panel frame, which is in a position reverse to that shown in Figure 2.

Figure 7 is anenlarged fragmentary vertical section through the upper end of my improved sash towards one vertical edge thereof, disclosing the preferred type of 'ivot bearings provided between the panel ame and the sash frame.

Fi ure 8 is a similar view taken through the pivotal connection between the upper end of the panel frame and the upper supporting arm between the sash frame and panel frame, disclosing the panel frame in one position within the sash frame, and L Figure 9 is a similar view, disclosing the illustrated in Figure 8.

Now having particular reference to the drawings, my novel sash consists of a frame 5 of predetermined dimensions, and adapted for slidable arrangement within the conventional window frame A. This frame 5 is formed at its inner edge and at its rear surface with a inwardly projectin flange 6, see Figures 7, 8 and 9. Mounte within this franie is a similarly shaped glass panel frame 7, within which is arranged and secured in conventional manner the lass panel 8. This panel frame .7 is formet? around its entire outer edge and at the outer surface thereof with a rabbet 9' for receiving the flange 6 of the sash frame 5 when said panel frame is in normal position, as illustrated in Figures 7 and 8, and will provide a weather-proof joint between the frames 5 and 7. The dimensions of the panel frame 7 is such as to provide a space between the upper and lower edges thereof and the sash frame 5, also as illustrated in Figures 7, 8 and 9.

The upper and lower inner surfaces of the sash frame 5 are equipped with metal channel strips 1010, mortised within the frame bgtween the flange 6 and inner surface there- 0 The upper and lower ends of the panel frame 7 at one side of thefra-me are equi ped with ball bearing sockets 11, within eadh of which is a ball bearing'12 for running enage'ment with the respective channel strip of t e sash frame" 5. This obviously therefor,

provides a sliding and swinging joint between the panel frame and said sash frame.

At the inner side of the frame 5 and adjacent one vertical edge of the frame there is rovided brackets 13-43, to which are loosey pivotally secured the inner ends of a pair m of arms 14--14 ofa length to enable the outer 1 ends thereof to be loosely pivoted as at 15 to: the direct center of the panel frame 7 at its upper and lower edges, as more clearly illustrated in Fi e 1. In order to allow the 15 outer ends 0 these arms to be properly ivoted to the panel frame, said ends thereo are offset inwardl as disclosed.

The panel ame 7 is equipped at its outer side and at one edge with a suitable pull 2o handle or knob 16 and obviousl whenever it is desired to reverse the po'sltion of the panel frame within the sash to'facilitate the washing of the outer surfaces of the glass panel, it is only necessaryto pull the handle, 2 which will cause the pivotal and sliding movement of the opposite end of the frame within the sash frame 5, as illustrated in Figure 1. By further pushing the panel frame, the reversepositionwill be brought about, as illusi so trated in Figures 6 and 9,

In view 0 the foregoing description when considered in conjunction with the accom- Eanymg drawings, it will be apparent that I ave provided a novel, simple and highly a: serviceable window sash that is well adapted for all of the purposes heretofore designated, and even though I have herein shown and described the most preferred embodiment of the invention, it is nevertheless to be understood j that minor changes may be made therein withp out departin om the spirit and scope of the appende claim. v

Having thus described my invention, what I claim as new, and desire to secure by Letters- Patent, i82.

In a window sash of the character described, a sash frame, a glass panel supportin frame arranged within said sash frame, sai sash frame, at its upper and lower sides bein provided with inwardly disposed oppose channels extending thereacross, pivot ,elements mounted on the upper and lower ends of the panel frame adjacent one side thereof and adapted to pivotally and slidably seat in the adjacent channel, and supporting and guidlng arms pivotally connected at one end to the upper and lower ends of, the panel frame centralgliyl thereof and at their opposite ends to the sa frame, said, panel supporting 00 frame adapted to be shifted to a reverse position in the sash frame.
